WINDOW-VENTILATOFLl To all whom it may concern.-

Be itv known that I, BUEL S. BURROUGHS, a citizen of the United States, residing at Kingston, in the county of Ulster and State of New York, have invented certain new and useful Improvements in Window-ventilators, of

which the following is .a specification, reference being had therein to the accompanyingdrawings, which form apart thereof.

My invention relates to window-ventilators, and more particularly to that class thereof l adapted to prevent condensation upon the v`window pane orplate in addition to providwhereby lthe lower bar of the window-sash ing a circulation of pure air within a windowseat, room, orother apartment.

The 'main object of the invention is to pro" videmeans of ventilation adjacent to a window-pane to prevent the accumulation of moisture and frost thereon due to the warm air within a window-seat, room, or apartment contacting with the chilled surface of the window pane or plate.

A further object is to provide means whereby water from the inside of the window pane or plate, whether such result from condensation thereon or from the cleaning of the window, will be collected and carried to the 'outside of the window-sash, thus avoiding the presence of water within the window-seat, room, or apartment.

A still further object is to provide means will be protected from the ravages of this water, as well as of the weather, so as to avoid premature decay thereof and the resulting danger due to a loosening of the pane or plate relative thereto.

A still further object is to provide means whereby the quantity of air placed in circulationI through theventilator may be conveniently regulated from within the apartment, and a still further object is to provide a device of this character'whieh will be simple-in construction, which will facilitate the mounting of the. pane-in the sash, which will be weatherproof, and which will be inexpensive to manufacture.

The invention'consists in the novel features of construction .and arrangement of parts hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings, Figure 1 is a Aview of the top and of the bottom of the eX- Speccation of Letters Patent. l Application iilecl January 18, 1905. Serial No. 241,566.

3 is a detail view in perspective ofthe pane-support and ventilator, and Fig. A is a similar view of the pane or plate cap and ventilator.

Like letters refer to like parts througlic-tv` "l the several'views.

The accompanying illustrations show the invention as appliedr to a display-front, in which a denotes the window-sash, the top and side bars of which are provided with the usual strips b for holding the pane or plate therein. Secured upon the, bottom bar of the sash a in any desired manner IV provide apane or plate support and ventilator which holds the lower edge of the pane or plate, thus dispensing with the bottom sash-strips ordinarily employed for this purpose. This support and Ventilator comprises abase c, adapted to rest upon and be attached or secured to the lower bar of the window-sash, as bythe fillet d, en-` tering a channel 62 in said bar. Approximately. centrally'of said base is a laterally-extending vertical web e, in which are a plurality of inlet andvent openings e', the lower edges of which are flush with the upper and preferably inclined surface of the base o. The part c of the base c outside said webprojects carry away water over the lower lbar of the window-sash, and that part 02 thereof within the web curves upwardly into a laterally-extended flange j', forming, with said web, a gut- The web e is surmounted by a head g, having parallel side flanges g' g ,forming a channel g2 in the `An arm j', moving in the gutter f and having a bearing j", conformingtoand adapted to upper face thereof adapted to receive and re- Ioo move upon the top of the flange f, is carried by said slide,1 which slide is controlledthereby, `a knob jg being provided on said arm for the convenient operationv of said slide.

The top of each flange g of the head g is beveled downwardly and away from the chanl A nel g2 insaid so asto' avoid an accumulation ofwater thereon adjoining' the pane or To insure a circulation of air within the window-seat, room, or apartment, I provide, in combination with the parts heretofore referred to, a cap and ventilator for the top edge of the pane or plate, which also serves to hold the top of the pane or plate with relation to the sash. This cap comprises a head Zt, adapted to pass between and be held by the top strips b', a web Z, having a plurality of vent-openings Zl therein, and a base m, presenting downwardly oppositelydisposed parallel flanges m', forming a channel m2, adapted to receive the top of the pane or plate, and thus serve to retain same relative to the top bar of the window-sash. Asliden, movable in parallel ways 0 0 in the head and base m, respectively, having a plurality of openings a therein adapted to register With the vent-openings Z in the web Z, and a controlling-knob p, are provided to regulate the size of the openings Z and the quantity of air passing therethrough.

The bottom support and ventilator and also the cap and ventilator are preferably cast of iron or other metal in a single piece and of a width of approximately one-half an inch wider than the standard widths of lights to provide the proper clearance on the sides corresponding with that ordinarily allowed in windowsashes, and the slides z'- and a are preferably cast in brass.

To obviate the difficulties arising from superficial inaccuracies and inequalities of the channel g2 due to the imperfections resulting from casting, I place in said channel a rubber or other similar or suitable packing-strip g3, which in addition to this function renders the lower edge of the pane or plate weatherproof.

In the application of my invention to a window the top edge of the pane or plate, as 7', is first inserted between the flanges m' m', so as to retain said cap upon said pane or plate, and the lower edge of said pane or plate is placed between the flanges g g of the support and ventilator. rlhe sides, the top bar, and the bottom bar and the ends of the side strips adjacent thereto of the sash having been prepared to receive, respectively, the side edges of the pane or plate, the head 7c, and the support or ventilator, the entire pane or plate and the bottom support, with the cap therewith, is raised into position relative to the sash, the head Zt of the top cap passing between the two top strips Z b to an extent to permit the fillet Z to pass over thebottom bar and enter the channel b2. The side strips are then secured to the sash. In storefronts or similar relations, where the weight and size of the light make it difficult to handle, straps may readily be placed through the inlet 0r vent openings e', thus serving to hold the support and the pane or plate together while mounting them in the sash and also facilitating such mounting. It will be observed that inasmuch as the said strap would not at any time be between the support and the lower bar of the sash it can readily be removed after such mounting.

The mode of operation of the herein-dcscribed structure is apparent from the foregoing description. Air in any desired quantities may be admitted through the inlet or vent openings e by moving the slide rz so as to regulate the size ofsaid openings. The gutter f will divert said air so as to bring it close to the pane, thus avoiding direct drafts. The heated air within the window-seat, room, or other apartment will rise and pass therefrom through the vent openings Z in quantities largely controlled by the regulating-slide n. The circulation of air thus produced will so equalize the temperature of both sides of the pane or plate as to avoid the condensation ofthe heated air thereon and in cold weather the accumulation of frost. Any water from the pane or plate will be collected in the gutterf and will drain through the inlet or vent openings e/ over the shield c', thus protecting the bottom bar of the window-sash and avoiding that premature decay noticeable especially in store-fronts. It will also be observed that the extended base c holds the pane or plate and that any loosening of the pane or plate could occur only through the disarrangement of the entire support through a partial or complete destruction of the entire bottom bar of the sash.

rIhe height of the side Hanges m/ f/ should be such relative to the space above the head Zt as to prevent such a vertical movement of the cap either alone or together with the pane or plate as would permit the said cap to be removed from the top edge of the pane or plate or to permit the pane or plate to be removed from the channel g2. The side strips, in conjunction with the fillet CZ and the channel 62, serve to maintain said support and ventilator in relation to the window-sash.

IVhile I have shown and described the invention as applied to a store-front, in which field I conceive it will have its greatest utility, it is apparent that it may be similarly applied in other connections by reducing the dimensions of the various constituent parts to conform to the desired application thereof. Its mode of operation in all such connections will remain substantially unchanged.

By reason of the construction herein described the device is inexpensive to manufacture and the air circulation therethrough may be readily controlled.

It is not my intention to limit the invention to the precise details of construction herein shown and described, such being capable of variation to adapt the invention to various analogous uses.

Having described the invention, what I claim as new, and desire to have protected by Letters Patent, ish
